 *
 * Replace all instances of <p> with <p/>. Just for the small number
 * of HMTL tags which don't require a matching end tag.
 * Also make HTML conform to the simple HTML requirements such as 
 * no double hyphens. Double hyphens are replaced by - and the character
 * entity for a hyphen.
 *
 * Cases where this fails and has to be corrected in the XML by hand: 
 *  Attributes' values missing their double quotes , e.g. size=-2
 *  Mangled HTML tags e.g. &lt;ttt> 
 *
 * <p><b>NOT USED</b>. There is often too much bad HTML in
 * doc blocks to try to handle every case correctly. Better just to
 * stuff the *lt; and &amp: characters with stuffHTMLTags(). Though
 * the resulting XML is not as elegant, it does the job with less
 * intervention by the user.
